To all whom "it may concern:

.Be it known that I, OLAF HETLESAETER, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented, certain new and useful Improvements in Shovel-Buckets, of which the following is a specification. 4 t i This inventionrelates to certain improvements in adigging member and the connectionsor mountings therefor. As shown in this case, the improvements areembodied in adipper or bucket, and embrace the-back and side reinforcingmeans, the hoisting connections attached thereto, the angular adjustingfeatures for the bucket,-and the dropdoor pivotpin mountingl Animportant advantage of -he hoisting connection is the reduced ex'en'seto replace in case one of the cables SllOl d break, as that Theequalizing bar is a valuable feature, for through the particularconnections shown, excessive Wear on the cables near the connectiorizIis obviated and thereby their life lengthene In the drawings,-Figure 1is a top plan view of the bucket, certain parts being re- Fig. 3 is -aview showing the hoisting rope connection to theequalizer bar.

The support or handle 1 has mounted at This dipper, w ich serves as areceptacle and also as adlgging member, has its back and side portionsnear the front well reinforced toward the lips where the greatest strainBetween-these two members is inserted. a connecting bar 4 which extendsthe full length of the dipper back. By this construction, not only anexceptionally strong structure is produced, but I am able by very littlealteration to vary the capacity of the dipper by changing the thicknessof this interposed draw bar 4. This is a quite advantageous featurebecause it obviates thene oessity of a difierent-set of patterns foreach capacity of dipper.

Rigidly attached to the dipper are the braces 5 which ermit of theadjustment of thedipper angul arly of the su port or handle 1 bymeans ofthe bolt 6 holes 7 in the handle 1. By this form of adjustment thePatented Dec. 31, 1907.

braces are of constant length, are not Weak ened by a joint norby holestherein, the

:plates on the support serving to reinforce this member where theholes 7are placed,

and fewer parts are required than have herei tofore been necessary. Asshown in Fig. 2 there are three holes 7 in the support 1. These holes 7are in the arc of a circle described about pin 17. When the braces-5 arement of the braces 5, the additional bolt 71 isunnecess'ary and wouldnot be used. The dipperhasthe teeth 8 and lip 9 which may be of theusual or any preferred form.

"Through the reinforcing elements 3 and i the bar 4 is inserted theequalizing bar 10 which has mounted thereon the shackle eyes 11 held inposition by keeper'plates 12 whicliare mounted on the keeper platevclamps 13.- Surroundingthe bar 10 is a bushing 14 serving as a bearingtherefor.

Mounted in the shackle eyes 1.1 and held in the clamp 13 is a hoistingcables 15.-

' To vhold the reinforcing, elements 3 and bar 4 in position, are aseries of boltslfi. Through this ribbed portion of the back of thedipper, and also through lateral lugs thereon, is a pivot pin 17. thesupport or handle is a' steel casting 18 having pivot bearing surroundinthe pin 17. Between the spaced ends .of the handle 1 is a dead-Wood 19for which may be substituted a reinforcing plat'el "lhe rear of thebucket has a drop-door 20, controlled by usual latch device.

This drop-door is also hinged on the pin 17 Having thus described myinvention,

What I claim and desire to secure by Letters Patent is,-

1. The combination of a digging member having a pair. of backreinforcing elements and a connecting bar.

2. The combination of a receptacle having a pair of back and sidereinforcing elements and an interposed connecting bar.

3. The combination of a digging member having a pair of reinforcingelements and a connecting bar interposed therebetween,

pair 'of flexible members or On the end of said bar extending member,and a pivot pin through the full length of said member. D

4. The combination of a digging member having a hinged side, a supportfor said member, and a pivot pin for the hinged side mountedin thesupport.

5. The combination of a digging member having a hinged side, a supportfor said the support, hinged'side and member.

6. The combination of a digging member, a support therefor, andadjustable braces rigid with the member and connected to the support.

7. The combination of a digging member, a support therefor, andadjusting means comprising a brace rigid withthe member.

8. The combination of a digging member, a brace, and a support havingholes whereby the member may be adjusted angularly with relation to thesupport.

9. The combination of having through said first na'med bar, and flexiblean I adjustable driven member, and a pair of flexible simultaneouslyoperating means connected thereto.

,10. The combination of a digging member, a pair of flexiblesimultaneously operatmg means, and an equalizing bar interposed betweensaid means and member.

11. The combination of ,a .swingably mounted driven member having a pairof reinforcing elements, an equalizing bar through said elements, andflexible operating means connected to the e ualizing bar.

1-2. The combination 0% a'bar at its back, an equalizer bar gperatingmeans connected to the equalizing In testimon in presence 0 twowitnesses.
